Can't play the app on Mac OS Sierra

[Nergus]

Hi, I managed to run the app on my Macbook M1 Pro, which means it works pretty well on Apple Metal processors, but I couldn't run the app on my 2013 Imac on Mac OS Sierra even with basic configuration files (which is a shame since the UT app works flawlessly on the same mac).

I actually managed to get it running on Mac OS Sierra but I had to launch the game on my M1 Pro Macbook, change the renderer from Metal to XSupport OpenGL (and not OpenGL because it crashes on this computer), then copy the System folder from Library/Application Support/Unreal and paste on my 2013 Imac running on Mac OS Sierra along with the game.

When it launches on Sierra, it works but the graphics are completely broken, so you have to go to the graphic settings and choose OpenGL or another renderer that works best on Intel based machines.

My suggestion would be to set the application to XSupportOpenGL by default, or OpenGL if you can fix it for Apple Silicon machines. Software rendering crashes the game too on Apple Silicon machines.

Could you test this with the new build I just uploaded?

Apple Metal renderer doesn't work on Intel from the getgo. Don't know if it's the same for everybody else or if it's only on my end though.

Oh it supports High Sierra but not Sierra, which is the version before High Sierra. Actually makes sense, don't think you could fix this detail really. Well thanks anyways, hopefully there are other renderers.

What settings did you use to get it to work on high sierra? I'm trying the same but I keep getting errors on launch.
